ABSTRACT:
An image of the separating plane of each of mold pieces of a metallic mold is picked up by a infrared vidicon camera before the mold pieces are closed together. That image is then processed so as to obtain a temperature distribution pattern which is in turn compared with a target temperature distribution pattern previously stored in memory. With the result of the comparison, the mold piece is cooled or heated so as to have the target temperature pattern before the mold pieces are closed together.
